Android: Flickr's own Android app is solid enough, but it leaves a lot to be desired. Glimmr, a new app from XDA forum user brk3, is not just better than the official app at viewing photos, it has tons of features the official app doesn't have.

If you're a heavy Flickr user, you'll appreciate Glimmr's gorgeous interface, support for Flickr groups, the ability to comment on photos, and the ability to view EXIF and location data. Compared to the official Flickr app, Glimmr actually makes browsing new photos from your contacts fun and interesting. The app will even notify you when your contacts upload new photos. The only downside to Glimmr is that it's definitely a Flickr browser—it can't upload photos or organize your albums. That said, when you authorize the app the first time you use it, you do grant Glimmr permissions to do this, so those features are likely coming soon.

The app is free at Google Play, although there's a $1.20 "pro" version that strips out the occasional ad and allows you to set images you see in the app as your phone's wallpaper.
